Read this machine's cross-machine mailbox, the messages another computer's agent left here over a file-synced bus folder, and send messages back the same way. A session-start hook shows new mail automatically; this is the on-demand mid-session re-check. Triggers: "/inbox", "check inbox", "messages from the other machine".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /inbox — mail between my own machines The "Claude on one machine → Claude on another" channel, over the synced `_machine-bus` folder (Syncthing, ~10s). It removes the human courier. Copy-paste by hand is an EMERGENCY channel only. ## Check what arrived for me (the main use) ```bash python "$USERPROFILE/.claude/scripts/machine_bus.py" read ``` Shows only what is NEW for THIS machine (matched by hostname) and marks it read. Then report to the operator what came in and act on it if needed. - At session start the `SessionStart` hook already does this automatically — `/inbox` is for when the operator says "check the inbox" mid-session (e.g. something new arrived over sync). - Re-check without marking as read: `... read --peek`. ## Send a message to Claude on ANOTHER machine 1. List the available mailboxes: ```bash python "$USERPROFILE/.claude/scripts/machine_bus.py" list ``` 2. Send: ```bash python "$USERPROFILE/.claude/scripts/machine_bus.py" send <RECIPIENT-HOSTNAME> "message text" ``` …

How to install
mdr add tonydzi/second-brain-starter-kit/inbox@sha256:cffbd4861996b22cThe line at the top of this page pins the label git:20261007.cd6c208, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
